Description: Vengeous is a large sentient sword created by Kakuzu himself using his dark threads and the heart of a fallen foe. The sword itself is two meters in length (including the hilt) and is the same width as a compacted Samehada. The entirety of the sword is composed of spiky black threads, and the exterior is tightly weaved together into a dense structure, which is impossible to cut through by normal means. The hilt of the sword is constructed of pure jade and shape of the blade of itself looks much like a curved arrowhead with its tip resembling a crab’s pincer. The heart inside of the sword is located in the center of the blade and is fully functioning, resulting in Vengeous being considered both a living creature and a sentient ally to Kakuzu. As a result Vengeous is capable of acting of its own accord, rational thought and has a malicious personality inherited from Kakuzu. The sword itself can go weeks without nutrition and has a strict diet of blood which it ingests through its skin. The sword is usually carried around in a black and red scabbard, on the user’s back.
-The sword is near impossible to break/cut through due to it’s tightly weaved exterior.
-The sword is capable of extending dark threads as tendrils to restrict and ensnare the opponent. These tendrils are capable of reaching up to five meters (short range) and can come from anywhere on the blade. The tendrils can pierce the bodies of other shinobi, can prevent the opponent's mobility by wrapping around them or even disarm a foe of their weapon. The amount of tendrils that can be released at any one time varies between 8 and 16. The tendrils themselves are each about the same width as a basic rope (ten centimeters) and all have sharp pointed ends. This is a B-Rank Ability
-The sword is capable of shooting out countless needles composed entirely of dark threads, which are about thirty centimeters in length and five times the width of a normal senbon. The needles can be shot from anywhere on the blade and have a mid-range reach (10 meters). This will count as one of the user’s jutsu per turn. This is an A-Rank ability
-The blade possess the ability to extend spikes from everywhere on the blade or hilt at any time, which are capable of skewering through the body of anyone they come into contact with. The spikes can reach up to two meters in length. Spikes which emerge from the blade resemble basic spears in both shape and width and the end result makes the sword look like its coated in an armour of spikes. Spikes which emerge from the hilt are much smaller, resembling needle-like thorns in shape and width. The spikes can be released at any time, adding a further element of surprise to the wielder's fighting style. Shortly after release the threaded spikes re-enter the sword, restoring the weapon's ordinary shape. This is an A-Rank ability
-The blade can use a limited amount of the elemental chakra present in its heart. It can use it to unleash blasts of pure elemental chakra (of the main elemental affinity of that heart) in various forms as both streams, blasts, projectiles, crescents, etc by swinging the sword. The sword can only use one element which is the main element of that heart. This ability is S-Rank.
-The sword is capable of crawling and acting independently
-Kakuzu is unable to use the heart of this sword for "Heart Reaper"
-The sword possess no mouth and isn't capable of talking but it does communicate with the wielder in an unknown form
-Must have a Kakuzu bio to wield the sword
-Vengeous is incapable of transferring chakra to the wielder
-The Sword can be killed by being burnt, melted or severely shocked. This makes the weapon extremely prone to death from Fire, Lightning and similar attacks, specially S-Rank and above.
-Negative Knight is the only person capable of wielding this weapon. In response to anyone else who attempts to wield the blade, the sword erupts in a violent outburst, extending 10 meter spikes from everywhere on its body (including the hilt), severely impaling the unsuspecting wielder.

-If the sword is severely damaged, the user can give it a heart and renew it.
